GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 593,760, dated November 16, 1897.

Application filed March 13, 1897- To ctll whom it nwly concern;

Be it known that I, GUsTAv A. BEACH- driven at a uniform rate of speed and addi-.

tional mechanism in the nature of a brake operable upon the shaft of the governor was provided to control the rate of speed at which the instrument was to be operated. In all such devices the application of the brake to slacken the speed of the governor caused the fiy-fans or weights to be brought nearer the center of rotation, which in itself would tend to allow the governor to be rotated at a higher rate of speed. For this reason great difiiculty has been experienced heretofore in providing an efficient governor, and it has been found impossible to provide a governor wherein the automatic action was not interfered with by the application of the brake or hand regulating device.

The object of my invention is to provide a governor wherein the objections heretofore encountered are overcome and which will be efficient under all conditions.

To these ends my invention consists in the novel arrangement and combination of parts hereinafter described and claimed.

In the accompanying drawing the representation is a side view of a motor for musical instruments, showing the application thereto $erial No- 627,280. We model.)

port f, to which are pivotally connected springs g. The opposite ends of these springs g, which are preferably leaf-springs, are pivotally connected to a sleeve h, which is adapted to slide-longitudinally upon the shaft 6 of the governor. To each of these springs g is connected a governing element, which preferably consists of a fly fan or wing 2', connected with a weighted semicircular piece j, which in turn is connected to a spring 9. An adj ustable collar is is carried upon theshaft of the governor between the movable collar h and the fixed support f, for purposes which will hereinafter appear.

A hand controlling or adjusting device 13 is pivoted at Land in the present instance is shown as comprising a yoke-arm m, which is adapted to straddle the governor-shaft e and to bear upon the sliding sleeve h. The other arm'n of this adjusting device B is provided with an operating-handle 0, which is accessible to the operator, and a suitable scale 13 is provided to indicate the position of the adjusting device. It is likewise desirable to provide means for maintaining the adj usting device in the position to whichit is moved against the tension of the springs g of the governor, and I have shown one means for this purpose. Thus q represents a series of studs which are adapted to pass in an aperture in the under side of the arm n of the adjusting device B when the said arm registers with the numeral on the index 19 and to maintain the adjusting device B in the position to which it has been moved by the operator. The yoke-arm m is preferably curved, as indicated at r, so that the least possible friction will be maintained between that portion of the adjusting device which bears upon the sliding sleeve 7% and the sleeve It is obvious that other means may the sprocket-wheel C to move slower, or, in other words, should it be desired that the tune be played slower, the adjusting device B is shifted to bring it to one of the higher numerals on the index, as at 2, for instance. This will result in the adjusting device forcing the movable sleeve toward the abutment 7;, thereby deflecting the springs g, with the wings i mounted thereon, outwardly from the 'center of rotation of the governor and thereby decreasing the speed thereof without preventing the automatic operation of the governor should an increased power be applied to the motor, which would necessitate a further expansion of the wings in order to provide a uniform rate of speed for the sprocketwheel 0. The adjustable collar or abutment k may be set to determine the greatest limit of expansion of the wings or the greatest limit to which said wings may be expanded either automatically or by the adjusting device 13.

Vhile I have shown and described my governor mechanism in connection with a motor for musical instruments, it is obvious that it maybe applied to other devices wherein it is found available.

In another application I have disclosed a governor mechanism having the same objects in view as those recited herein and have elected to embody generic claims in the other case.

hat I claim, and desire to secure by Letters Patent, is

1. In a governor mechanism, the combination of automatically-expanding governing elements mounted upon springs,each of which is fixed against longitudinal movement at one end and controlling means for deflecting said springs from the free ends thereof.

2. In a governor mechanism, the combination of automaticallyexpanding wings, springs upon which said wings are mounted, each of said springs being fixed against longitudinal movement at one end, controlling means for deflecting said springs from the free ends thereof outwardly from the center of rotation of said governor and means for retaining the controlling means in the position to which it is moved.

3. In a governor mechanism, the combination of automatically expanding wings, springs upon which said wings are mounted, each of said springs being fixed against longitudinal movement at one end, a movable sleeve to which said springs are connected at the free ends and controlling means for moving said sleeve to deflect the springs.

i. In a governor mechanism, the combination of automaticallyexpanding wings, springs upon which said wings are mounted, each of said springs being connected at one end to a movable sleeve and fixed against longitudinal movement at the other end, handoperated adjusting means for moving the said sleeve in one direction in opposition to the tension of the springs and means for retaining the hand-operated adjusting means in the position to which it has been moved.

5. In a governor mechanism, the combination of automatically expanding wings, leafsprings g upon which said wings are mounted, each of said springs being pivotally connected at one end to a movable sleeve carried upon the'governor-shaft and being pivotally connected at the other end to a support fixed upon said shaft, hand-operated adj usting means for moving the said sleeve in one direction in opposition to the tension of said springs, adjustable means for limiting the movement of said movable sleeve and means for retaining the hand-operated adjusting means in the position to which it has been moved.
